FMOD , though last time I checked, there are not any 'non commercial' bindings for it? Though apparently its quite awesomeIts free for 'free projects' but costs at least $500 for a commercial indie license

JOAL or JNI maybe?

While I do not have any actual experience or knowledge in this area. Could I ask why you wanted an alternative?Is there a problem/shortfall that you are unsatisfied with openAL?
